When I bought my truck I was still surprised to see a 100 mph speedometer. Did they change it to 120 mid year of 2017, I just caught a video of a 2017 with a 120 mph speedometer.
Just to add to this, I had a 2014 KR which had a 120 and I now have a 14 platinum that has a 100. The KR truck was made in Canada/shipped to Canada. I've verified this many times, trucks with the Canadian leaf on the VIN tag on the driver's door always had a 120mph speedo.
